As stated the games are very strict with promotional activity. There is no way they would allow Bugs Bunny to just pop up at an event, they don’t even allow you to take in pre-packed food (chips, drinks etc) because of the branded logos on the packets - you have to empty them into clear bags/containers before entering a venue.
With sponsorship deals starting at over $2million for 11days, I’d much rather the parks keep the money for future attractions which will do way more for drawing in the crowds.
